Coupled Optimization of Diode and IGBT Characteristics Under Clamped Inductive Switching in ATLAS MixedMode and Virtual Wafer Fab (VWF)<\/h1>\n

Abstract<\/h2>\n

Virtual Wafer Fab\u2019s powerful range of optimizers are used to investigate and minimise the coupled switching losses of a TCAD IGBT and its clamping diode in a chopper circuit. It is shown that it is vital that the designer concurrently optimizes both the switching losses of the IGBT and the clamping diode in a single operation.<\/p>\n

Introduction<\/h2>\n

One of the fundamental goals when designing power devices is to minimise the energy losses. Device designers will commonly consider the turn-off loss v\u2019s on-state loss trade-off curve [1]. An optimized, stand-alone device is typically considered to be on where its forward voltage drop \/ turn-off loss characteristics lie around the knee of the trade-off curve.<\/p>\n

Although this is simple and fast, in reality these devices are to be used inside circuits. The devices will be coupled with other devices and parasitic elements. Furthermore, just because a stand-alone device is optimized it does not mean that when incorporated in a circuit the device parameters previously decided upon are still optimum in terms of energy loss [2].<\/p>\n

In this article a very similar methodology to that found in [2] is followed. The principle difference is that the IGBT and clamping diode are TCAD devices created in ATLAS and the clamped inductive switching (CIS) is undertaken in MixedMode rather than the MATLAB\/Simulink environment as was the case in [2]. Furthermore, for the optimization experiments, Virtual Wafer Fab (VWF) was used. VWF is a commercially available tool that can be used for Design Of Experiments (DOE) and multi-target optimization experiments packaged in a user friendly GUI.<\/p>\n
